TECHNICAL FIELD

The present invention relates to an ice tray and, more particularly to an ice tray assembly used for producing clear ice shapes.

BACKGROUND

Generally, ice trays are used for producing ice shapes such as ice cubes for domestic purpose or for commercial purposes. The use of conventional ice trays leads to the formation of ice cubes with air trapped inside the ice cubes. Due to the trapped air, the ice cubes appear white instead of clear. The conventional ice trays generally do not separate the ice cubes from the trapped air and the ice cubes appear white.

There are some conventional clear ice producing trays, however their yield to produce clear ice is low, and such trays are not capable of producing clear ice of different shapes and of high quality. Also, design of the conventional clear ice producing trays makes the extraction of the clear ice from the trays difficult and time consuming.

In view of the above shortcomings, there is a requirement for an ice tray assembly that produces clear ice shapes with high yield and with less extraction time from trays.

The top ice tray includes a first plurality of mold cells for forming clear ice shapes from water present in the first plurality of mold cells. Each mold cell includes an open top end and an open bottom end. The middle layer is adapted to be sandwiched between the bottom tray and the top ice tray. The middle layer includes a plurality of perforations to pass free flowing oxygen from the top ice tray to the bottom tray. One or more latches are coupled at least with the bottom tray and the top ice tray, to hold the bottom tray and the top ice tray together. The clear ice shapes are produced in the first plurality of mold cells when the free flowing oxygen from the top ice tray passes to the bottom tray through the plurality of perforations in the middle layer.

In another embodiment, an ice tray assembly for producing clear ice shapes is disclosed. The ice tray assembly includes a housing, a bottom tray, a middle layer and a top ice tray.

Overview

Various embodiments of the present disclosure provide an ice tray assembly primarily used for forming high quality clear ice. The ice tray assembly also helps in easy extraction of the clear ice. In one configuration, the ice tray assembly includes a housing, a bottom tray, a top ice tray, a middle layer and one or more latches. The housing is insulated and has an open top end. The insulated housing allows the cold air to flow only in a top down direction leading to the directional freezing of the ice tray assembly. The housing includes grooves and acts as a support for other components of the ice tray assembly, for example a stacked combination of the bottom tray, the middle layer, the top ice tray and the latches is placed within the housing.

The top ice tray is disposed above the bottom tray and includes a first plurality of mold cells having an open top and an open bottom. The clear ice shapes are formed in the mold cells of the top ice tray forms upon freezing of the water present in the mold cells. The middle layer is sandwiched between the top ice tray and the bottom tray and acts as a base for the top ice tray. The middle layer includes a plurality of perforation. The perforations separate the free flowing oxygen from the top ice tray. The middle layer is removable, thereby helps in easy extraction of the clear ice shapes. The bottom tray is adapted to catch the free flowing oxygen from the top ice tray. The bottom tray includes a second plurality of mold cells to form scrap ice shapes upon freezing of the water present therein. The second plurality of mold cells has an open end and closed bottom. The second plurality of mold cells can have different shapes as long as the volume of the bottom tray is greater than the volume of the top tray. The latches are configured to hold the top ice tray and the bottom tray together within the housing.

Once the latches engage with the top ice tray and the bottom tray with the middle layer sandwiched between the top ice tray and the bottom tray, the latches form a water tight seal, and the combination is placed inside the housing and water is poured into the ice tray assembly. The middle layer allows the free flowing oxygen from the top ice tray to flow to the bottom ice tray and thereby leading to the formation of clear ice in the top ice tray and scrap ice shapes in the bottom tray. Once the water in the top ice tray is completely frozen, the ice tray assembly is removed from the freezer and then from the housing, and is allowed to thaw for some time. The removable middle layer helps in convenient extraction of clear ice shapes from the top ice tray without causing any damage to the clear ice shapes.

FIG. 1 illustrates a perspective view of an ice tray assembly 10 in a utilized state, according to an embodiment of the present invention. In operation, the ice tray assembly 10 is placed inside a freezer (not shown) for the formation of clear ice shapes. Various components of the ice tray assembly 10 are described with reference to FIGS. 2 to 8.

FIG. 2 illustrates an exploded view of the ice tray assembly 10, according to an embodiment of the present invention. The ice tray assembly 10 includes a housing 15, a bottom tray 20, a top ice tray 25, a middle layer 30 and one or more latches 35. The housing 15 provides support to other components of the ice tray assembly 10. The ice tray assembly 10 is shown to have included the above stated components in a specific configuration, however, those ordinarily skilled in the art would appreciate that the ice tray assembly 10 may include slightly different configurations of the above stated components.

During assembly, a stacked combination of the bottom ice tray 20, the middle layer 30, the top ice tray 25 along with the latches 25, is disposed within the housing 15. The bottom tray 20 acts as a base for the top ice tray 25. The top ice tray 25 is disposed over the bottom tray 202 in a configuration such that the middle layer 30 is sandwiched between the top ice tray 25 and the bottom tray 20. The combination of the bottom tray 20, the middle layer 30 and the bottom ice tray 25 are held together by the one or more latches 35 and thereafter the combination is placed inside the housing 15.

Once the combination of the bottom tray 20, the middle layer 30, the top ice tray 25 and the latches 35 are disposed inside the housing 15, water is poured into the ice tray assembly 10. The water enters the ice tray assembly 10 through the top ice tray 25. The middle layer 30 has a plurality of perforations that allows the water and the free flowing oxygen from the top ice tray 25 to flow towards the bottom ice tray 20, thereby leading to formation of clear ice shapes 40 in the top ice tray 25. Scrap ice shapes 45 may be formed in the bottom tray 20.

After the ice tray assembly 10 is filled with water, it is placed inside a freezer. Once the water in the top ice tray 25 is completely frozen, the ice tray assembly 10 is removed from the freezer and then the combination of the bottom tray 20, the middle layer 30, top ice tray 25 and the latches 35 is removed from the housing 15 and made to thaw for a few minutes. The combination is easily dissembled by removing the latches 35 and the bottom tray 20. The middle layer 30 can be removed by peeling off, making the extraction of the clear ice shapes 40 from the top ice tray 25 very convenient.
